RATGI-IET GREASE-CUP.

To all whom it may comma:

Be it known that I, GEORGE WV. BOWEN, of Auburn, in the county of Cayuga and State of New York, have invented a new and useful Ratchet Grease-Cup, of which the following is a specification.

My invention relates to grease cups and has for its object a ratchet grease cup which is particularly simple in construction, economical in manufacture and highly eflicient in use; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional View of my grease cup. Figs. 2, 3 and 4: are detail views of parts thereof. Fig. 5 is a detail view of the diaphragm or holding disk in the base of the grease cup.

1 is the base, and 2 is the cap of this grease cup, said parts being usually stamped from sheet metal. Preferably the base comprises a funnel-shape body 3 having an upturned cylindrical flange 1 which is externally threaded, and the cap is formed with an imperforate head and with an internal thread turing on the threaded portion of the base, said internal thread terminating short of the inner face of the imperforate head.

5 is a disk fixed within the cap, this disk being preferably stamped from sheet metal and having a threaded edge coacting with the internal thread of the cap and being screwed into the cap toward the head 6 of the cap.

7 is an abutment ring which is interposed between the inner face of the head 6 and the margin of the disk 5 and limits the inward movement of the disk 5, and together with said disk and the inner face of the head 6 confines a chamber 8. The ring 7 is thus fixed in the cap as turning of the cap on the base to compress the grease in the cup serves to more tightly jam the disk against the abutment ring 7, and the spring, to be described, of the ratchet mechanism of the disks 5 and 9 is not sufliciently strong to lock the coacting disks of such mechanism together and cause the cap to turn relatively to the disk 5 when the cap is being unscrewed.

9 is a ratchet disk located within, and formed of substantially the same diameter Specification of Letters Patent.

as the chamber 8 formed by the disk 5, ring 7, and the inner face of the head 6 of the cap, said disk 9 being movable in the chamber 8 independently of the cap 2 lengthwise of the axis of said cap and coacting with an axial non-circular stem 10 extending through a non-circular opening 11 in the disk 5, and of greater diameter than the stem 10, the stem being spaced apart from the inclosing wall of the opening 11 and fitting a non-circular opening 12 in a diaphragm or holding disk l3 fixed in the base 1 and usually within the upturned cylindrical flange of the body portion of the base. The stem 10 is held by the disk 13 from turning movement with the cap and holds the disk 9 from such turning movement. Said stem 10 is preferably formed with a shoulder 110 engaging the outer face of the disk 9, and with a reduced inner end extending through and projecting inwardly beyond said disk 9. Preferably the lower end of the stem 10 is pointed for facilitating its entrance into the opening 12, and said lower end projects sufficiently beneath the edge of the open end of the cap so that said stem enters the opening 12 and centers the cap before it engages the flange 1 of the base. Opposing faces of the disks 5 and 9 are provided respectively with coacting proj ections 1 1 and depressions 15 forming ratchet means. The disks 5, and 9 are pressed toward each other by a leaf spring 16 rigidly mounted on the upper face of the disk 9, the central portion of the spring 16 being spaced apart from the inner face of the head 6 of the cap 2 and bearing against the inner or opposing surface of the central portion of the disk 9 and the shoulder 110,

and having an opening which receives the extremity of the reduced end of the stem 10, and said extremity being riveted upon the contiguous or inner face of the spring 16. Said spring 16 is discoidal and curved out of a plane and its spaced apart ends bear against the inner face of the head 6 of the cap.

The diaphragm or holding disk 18 is formed with perforations 17 therein for permitting the grease to pass from the cap through the base, these perforations 17 being spaced apart from, that is not communicating with, thecentral opening 12 of the holding disk.

In operation the cap is held in its adjusted position and from being accidentally e turned by vibrations or other conditions by the fact that the engaging means 14 and 15.

cap other than threading and riveting is necessary, as the projections and depressions on the ratchet disks are formed while said disks are being stamped out.

It will be noted that the disk 9 is supported on the disk 5, that the disk 9 supports the stem 10 and the spring 16, that these parts 9, 10 and 16 are united together and when secured together, as shown, are assembled in position by passing the stem 10 through the opening 11 in the disk 5 and screwing said disks 5 within the cap 2 against the abutment ring 7, and that when the parts 9, 10 and 16 are assembled within the cap, said parts 9 and 10 move together whenever the disk 9 is forced in one direction against the spring 16, or in the opposite direction by such spring. It will also be noted that my present invention does not necessitate a particular construction of cap, but, on the contrary, uses a well known form of cap and merely requires that the ring 7 the disk 5, and the parts 9, 10 and 16 shall be assembled within such cap.
